MACHINE FOR BREAKING AND SHAKING HEMP.

SPECIFICATION forming part of Letters Patent no. 622,433, dated April 4,1899.

Application filed July 25, 1898. Serial No. 686,819. (No model.)

To all whom, it may concern:

Be it known that I, ALBERT ANGELL, acitizen of the United States,residing at Orange, county of Essex, State of New Jersey, have inventedcertain new and useful Improvements in Machines for Breaking and ShakingHemp, fully described and represented in the following specificationandthe accompanying drawings, forming a part of the same.

The present invention relates to that class of hemp-brakes in which thehemp-stalks are broken over the edge of the break-bar'and aresubsequently beaten and scraped by the slats of a revolving beater toloosen the pith and bark therefrom; and the object of the presentinvention is partly to arrange the revolvingbeater below the top of thebreak-bar, so that the crushed fibers may be delivered to the beater bya leather flap, which is vibrated by the beater-slats, and thus shakesthe fibers during the cleaning operation.

Another object of the invention is to separate the pith and bark fromthe stalks before they are subjected to the revolving beater, which iseffected by the'vibrations of the said flap.

Another object is to remove the pith and bark which are shaken from thefibers and to prevent such materials from falling upon the beater-drum;and this object is-accomplished by an apron extended transversely-abovethe drum adjacent to the vibrating flap.

Another object of the invention is to facilitate the shaking of thefibers after they are subjected to the revolving beater to shaketherefrom the broken pieces of wood or shives; and this object isaccomplished by providing delivery-rolls adjacent to the beater andextending a leather or flexible funnel from the opening of such rolls.The fibers are delivered through such funnel, and the latter is vibratedlaterally, so as to shake the fibers as they pass from the machine.

In carrying out this invention the feedboard of the machine ispreferably inclined upwardly to the feed-rolls, which constructionpermits the elevation of the rolls and the arrangement of thebeater-drum below the break-bar at a suitable height from the ground toaccommodate the chaff which falls beneath the operative parts of themachine.

These improvements greatly facilitate the feeding of the stalks to themachine and clean the fibers in the most effective manner, while theyalso protect the operator from the dust and chaff which are beaten fromthe .stalks.

' The invention will be understood by reference to the annexed drawings,in which Figure 1 isa cross-section at the middle line of Fig. 2,'andFig. 2 is a plan of the apparatus with the top cover removed. Fig. 3 isa plan on line 3 3 in Fig. 1. Fig. 4 is an elevation of the machine,viewed from the righthand side,with reference to the feeding-board G;and Fig. 5 is an elevation of the left-hand side.

The machine is constructed with two side frames A, having bearings forthe shafts of the different rolls and drums. The beaterdrum B is mountedupon shaft B at about the middle of the frames, and the break-bar O issecured atits opposite ends to the frames and set a little above and atthe right of the.

is inclined downwardly and forwardly from the outer side of theguide-roll. The lower side of the break-bar is provided with anangle-bar b, which serves to strip the stalks from the rear feed-rolland direct them upwardly across the face of the break-bar. A break-drumH is mounted upon a shaft H, which is located over the front edge of thebreak-bar, and the break-drum is provided with blades h, which break thestalks over the upper front edge of the bar and throw them backwardly. Aflexible flap I, formed of leather or equivalentmaterial, is attached tothe rear side of the break-bar and extended backwardly over thebeater-drum B. In such position the weight of the fiap throws itdownwardly against the slats b of the beaterdrum, which'throw itintermittingly upward, and thus vibrate it rapidly. Adjacent to the freeedge of the vibrating flap an apron J is extended transversely acrossthe machine over the tops of the frames, which are cut down at suchpoint close to the top of the beater-drum. The apron is mounted uponrolls and 7a, the latterbeing supported outsideiof the frame bybearingsj and the apron traversed toward such rolls, so as to deliverthe chaff beyond the frame upon the ground. In this location the apronreceives the wood and shives which are beaten from the stalks by thebreak-drum H and also the pith and bark which are shaken from the fibersby the vibrating flap I, the chaff which is cleaned from the fibers bythe beater-drum B being thrown downward beneath the machine. A cover Kis extended over the beater-drum and apron and downwardly at the rearside of the same to confine the chaff thereto, the cover being open atone end over the roll 70, where the chaff is discharged. A pair ofdeliveryrolls L is mounted upon shafts L (at a common level) at the sideof the beater-drum opposite to the feed-rolls, and a guide-roll M isarranged upon'a shaft M above the deliveryrolls to guide the fibersthereinto as their forward ends are advanced over the beater-drum. BarsN are extended between the frames A beneath both of the rolls L to formlongitudinal supports for a leather funnel O, which is extended downwardfrom the opening of the delivery-rolls, so that the beaten fibers passthrough such funnel. The lower end of the funnel is contracted to justpass the fibers, and a bar 0 is attached to one side of such end andconnected with vibrating rods 1), which are actuated by eccentrics 1)upon a rapidly-revolving shaft P. The shaft P is connected with theshaft E of the guide-roll E by gears 6, one of such gears being drivenby a pinion 6 upon the break-drum shaft H, as shown in Fig. 5. The samegear 6 is also meshed with a gear on upon the shaft of the guide-roll M.The feed-rolls D are geared together and to the guide-roll E by gearsd,and the delivery-rollsL are geared together and to the guide-roll M bygears l. The shaft M is geared to the shaft J of one of the apron-rollsby worm-gearing J 2 J 3 s s, and all the parts of the machine are thusrotated at suitable speeds, the drums B and H at a high rotatingvelocity and the rolls and apron at a much slower speed. Shafts B and Hare connected by gears Q and driven by pulley R.

Operation of the machinc.The stalks F are fed upwardly by the rolls Dacross the front face of the break bar 0 and when broken by the drum Hare driven backwardl y over the flap I. The flap beats them by itsvibrations and throws the wood and shives upwardly upon the apron J. Asthe fibers F pass from the vibrating end of the flap they fall upon thebeater-drum B, whose slats I) scrape and beat the fibers and dislodgethe particles of pith and bark therefrom. The

delivery-roll nearest to the beater-drum is.

covered with a layer of india-rubber, as shown in Fig. 2, and serves todraw the loose fibers from the periphery of the druminto the spaceadjoining the guide-roll M. The fibers are thus guided downwardlybetween the delivery-rolls into the funnel O, which, being made ofleather, india-rubber packing-cloth, or equivalent flexible material, isrigidly secured at its upper edge to the bars M, while its lower edge isvibrated rapidly by the connecting-rodsp. The fibers are thus shakenviolently as they pass through the funnel and the dirt and chaif arethoroughly separated therefrom by such vibrations. An operator catchesthe fiber as it comes through the funnel, or it may be caught anddelivered by a traveling carrier. \Vhen the rear ends of the stalks havepassed over the break-bar, the fibers are driven downwardly by therotation of the beater-drum, as shown at f, between the beater-drum andthe nearer delivery-roll, and the forward ends of the fibers are thenpropelled by the delivery rolls, their rear ends receiving a continuedbeating by the drum B until they are drawn entirely through thedelivery-rolls. v

lVith the construction described it will be observed that the stalks arefed directly upward across the front side of the break-bar O, in whichposition a large part of the wood and shives (which are loosened by thebreakdrum) is enabled to fall away from the stalks upon the outer sideof the break-bar and is not therefore carried toward the beater-drum toclog the same. To effect this operation, one of the feed-rolls D isplaced directly underneath the break-bar O and the center of thebreak-drum shaft H is placed directly over the front edge of thebreak-bar, so that the stalks are fed directly against the bottom of thebreak drum. After the fibers are broken upon the break-bar they aresubjected to a shaking and beating three separate times in theirprogress through the machineefirst, by the vibrating flap I; second, bythe periphery of the beater-drum B, and, third, by the vibrating funnel0. It will be observed that the rear ends of the stalks are beaten bythe drum B the same as the forward ends after they have passed thebreak-bar, as they then hang down between the elastic surface of thedelivery-roll L and the slats of the beaterdrum, which are adjusted totouch the elastic body of the roll.

Having thus set forth the nature of the invention, what is claimedherein is- 1. In a hemp-brake, the combination, with the revolvingbeater-drum B, the break-bar 0 arranged above the top of the drum at oneside of the same, and the break-drum H having shaft H arranged above thefront edge of the break-bar, of the pair of feed-rolls D arranged at acommon level, with one of them underneath the break-bar as set forth,the guide-roll E below such feed-rolls, the feeding-board G inclineddownwardly from such guide-board, and the rolls operated to feed thestalks directly upward in the front of the break-bar against the lowerside of the break drum, as and for the purpose set forth.
